Abstract
The eccentric blade rotor rotary engine is internally divided into a compression section, a combustion chamber, and a power section. Each rotor device of a compression/power section is made up of a rotor body and three swing blades. Each swing blade is pivotally connected to the rotor body and may swing about a pivot pin. The rotor body and the swing blades of the rotor device are each formed by jointing a left half and a right half. The left half and the right half have joint surfaces in which at least one recess is formed in an opposing manner to receive an elastic element. The elastic element provides an outward pushing force to the left half and the right half. Under the high temperature operation, the rotor body and the swing blades expand due to the heat and thus compress towards the center whereby sufficient looseness may be presented between the rotor body and the swing blades and a cylinder wall to ensure smooth operation. Each swing blade comprises a cylindrical roller mounted to a front end and a curved back, and each of the rollers is provided, at an inner side, with a support device that is capable of sustaining a counteracting force applied by a cylinder wall to the roller. Thus, the frictional force between the roller and the support device is reduced. Since this novel design delivers a more efficient engine that will help to reduce fuel consumption and CO2 emission in transportation industries.
